Kukhona ezinyeiintsomi eziqhelekileyomalunga nokufunda iiglasi.
Enye yezona ntsomi zixhaphakileyo: Ukunxiba iiglasi zokufunda kuya kubangela ukuba amehlo akho abe buthathaka. Oko akuyonyani.
Enye intsomi: Utyando lwe-cataract luya kulungisa amehlo akho, oko kuthetha ukuba ungalahla iiglasi zakho zokufunda. Oko akuyonyani. Usenokuba neengxaki zokubona ezingabonakaliyo ezingenakulungiswa ngeeglasi zokufunda.
Kwaye kukho ingcamango yokuba ukufunda iiglasi kwenza umntu onxibeyo abonakale emdala. Iingcali zokhathalelo lwamehlo ziyayigatya loo nto njengendlela endala yokujonga iiglasi zokufunda, ingakumbi xa ucinga ukuba abantu baseMelika abangaphezu kwezigidi ezili-150 banxiba iiglasi ezilungisa umbono.
Zithini iiglasi zokufunda?
Iiglasi zokufunda, ezifumaneka ngaphandle kwekhawuntara okanye kwiinguqulelo zikagqirha, ziphucula ubuchule bokufunda into kufutshane, njengencwadi okanye isikrini sekhompyutha.
Iiglasi zokufunda ezithengiswa ngaphandle kwekhawuntara — ezinokuthengwa kwiivenkile zamayeza, iivenkile ezinkulu kunye nezinye iivenkile ezithengisa izinto ngaphandle kwemvume kagqirha — zenzelwe ukunxitywa ixesha elifutshane, kwaye zilungele abantu abanamandla afanayo eelensi, okanye amandla, kwiliso ngalinye kwaye abangenawo.i-astigmatism, imeko eqhelekileyo ebangelaumbono ofipheleyo.
Amandla eelensi eeglasi zokufunda ezithengiswa ngaphandle kwekhawuntara zihlala ziqala kwi +1 ukuya kwi +4. Iiglasi zokufunda ezithengiswa ngaphandle kwekhawuntara ziyindlela eyamkelekileyo kubantu abanombono olungileyo womgama (ukubona kude).
Nangona kunjalo, ukuba unesifoukukhathala kwamehlo ekhompyuthaokanyeumbono ophindwe kabini, ke ngoko bubulumko ukuhlola iiglasi zokufunda ezisetyenziswa ngugqirha.
Iiglasi zokufunda ezisetyenziswa ngugqirha wezilwanyana zenzelwe ukunxitywa ixesha elide, kwaye zilungele abantu abane-astigmatism, i-myopia, iingxaki zamehlo ezinzulu okanye amandla angalinganiyo kagqirha wezilwanyana kwiliso ngalinye.
Udinga nini iiglasi zokufunda?
Phantse nabani na okwiminyaka yabo engama-40 nangaphezulu, ngaxa lithile, uya kufuna iiglasi zokufunda (okanye olunye uhlobo lokulungiswa kokubona kufutshane).
Iiglasi zokufunda zinceda ekunciphiseni umbono obuthathaka onxulumenei-presbyopia, ukulahlekelwa okuqhelekileyo okunxulumene nobudala kokukwazi ukugxila kwizinto ezikufutshane, njengamagama encwadini okanye umyalezo obhaliweyo kwifowuni ephathwayo.
Ngokwesiqhelo uyayiqonda imfuneko yokufunda iiglasi ukuba unengxaki yokufunda umbhalo omncinci xa udiniwe kwaye xa izibane egumbini zincinci, okanye ukuba ufumanisa ukuba kulula ukufunda into xa uyitsala kude nobuso bakho.
Ijolise kumaqela ahlukeneyo neemfuno, i-Universe Optical ivelisa uluhlu olubanzi lweelensi ze-optical kuzo zonke ii-index kunye nezixhobo ezahlukeneyo, unokuhlala uthembele kwaye ukhethe iglasi efanelekileyo kuwe.
